Summary:                    transfer number of caller to callee when doing
attended transfer
Description: 
I asked on the #asterisk IRC channel, and I was told that this is not
possible right now, so I do a feature request.

With a blind transfer, the callee will see the number of the original
caller.
But when doing an attended transfer, then the callee only sees the number
of the person transferring the call.

When the call ends, and the callee wants to call back, he cannot easily
lookup the number in the call record log in his phone, and then just call
back.
In the worst case, he has to call the person that transferred the call,
asking for the number.

There are at least two ways of doing attended transfers.  If you do a SIP
attended transfer, the enquiry call is indistinguishable from a new
incoming call until the transfer gets committed.  By the time the transfer
is committed, it is too late to update the calling line ID, at least for
some destination technologies.  It would be up to the SIP phone, itself, to
provide the correct calling line ID in that case.

For the case where it could be done, i.e. using dialled digits and the
features module, one still has to consider a couple of cases:

1) the transferror is a secretary who is screening calls, and the boss
does not want to take calls that have been direct dialled to bypass the
secretary;

2) the call isn't really a transfer, but is actually an enquiry by a user
acting as a broker; in that case they may not want to reveal the identity
of their client (there may be cases where this is important even when the
transfer gets committed).

For both the above reasons, I think any such feature would have to be
optional.

Incidentally, as I understand it, feature requests can only be made
against version 1.6 (or trunk) at the moment.
